soareschen has just created a new issue for https://github.com/w3c/webrtc-pc:
== Default values for RTCRtpEncodingParameters ==
The current definition seems to imply that all fields are optional and have the value `undefined` if not set. However it seems that at least some of the fields should have default values, e.g. `active` and `priority`.
For example, the following examples have different `active` values:
```javascript
// sender.encodings[0].active == true
pc.addTransceiver('audio');
// sender.encodings[0].active == true
pc.addTransceiver('audio', { sendEncodings: [] });
// sender.encodings[0].active == undefined
pc.addTransceiver('audio', { sendEncodings: [{}] });
```
